“…The proposed method was accompanied by the desired advantages of a reduction in analysis time, an increase in the number of processed samples, and the lack of need for mechanical stirring due to the effervescence by CO 2 bubbles, which aided in the extraction of the analytes with detection limits (ng L −1 ) ranging from 17 to 79 for halo acetonitriles, from 10 to 35 for trihalomethanes, from 12 to 220 for halo nitromethanes, and 10 to 16 for halo ketones. The enrichment factors ranged from 13.1 to 140.1 and recoveries from 80 to 113% [75]. Table 4 describes some powerful applications of HF-LPME in different matrices.…”

Liquid phase-based microextraction techniques (LPµETs) have attracted great attention from the scientific community since their invention and implementation mainly due to their high efficiency, low solvent and sample amount, enhanced selectivity and precision, and good reproducibility for a wide range of analytes. This review explores the different possibilities and applications of LPμETs including dispersive liquid–liquid microextraction (DLLME) and single-drop microextraction (SDME), highlighting its two main approaches, direct immersion-SDME and headspace-SDME, hollow-fiber liquid-phase microextraction (HF-LPME) in its two- and three-phase device modes using the donor–acceptor interactions, and electro membrane extraction (EME). Currently, these LPμETs are used in very different areas of interest, from the environment to food and beverages, pharmaceutical, clinical, and forensic analysis. Several important potential applications of each technique will be reported, highlighting its advantages and drawbacks. Moreover, the use of alternative and efficient “green” extraction solvents including nanostructured supramolecular solvents (SUPRASs, deep eutectic solvents (DES), and ionic liquids (ILs)) will be discussed.

“…Offline sample preparation with 3D-printed devices that have been, or can be, coupled to MS detection are presented in Table 2, and mainly focus on ultrafiltration [70], SPE (Fig. 2AeB) [18,57,58,71,75], liquid-phase micro-extraction (LPME) [73,76], or creating devices for integrated, high-throughput sample pretreatment (Fig. 2C) [77e79].…”

“…Moreover, as samples can be immediately submitted for the analysis, the time from sampling to answer can be decreased. Given the fact that most of the applications of these devices fall into medical research [58,70,77e79], or environmental safety [18,57,71,73,76], where sample is gathered outside the lab and thus normally needs to be collected, stored and brought to the laboratory, such an offline approach is perfectly justified. While some of the reported devices have been demonstrated in an offline mode, they could be used in an online fashion as well (e.g.…”

“…In fact, turbulence caused by the formation of CO 2 bubbles in the liquid facilitates natural mixing, which eliminates or reduces the need for mechanical stirring and shortens the extraction time. This method resulted in high reproducibility due to lack of contact between the fiber and the vial surface, thereby removing cross-contamination problems [61].…”

CO2-Effervescence in Liquid Phase Microextraction for the Determination of Micropollutants in Environmental Water: a Review

et al. 2021

View full text Add to dashboard Cite

Liquid phase microextraction is a state-of-the-art micro-analytical work with numerous advantages documented in the scientific literature. One of the most intriguing subclasses is the CO 2 -effervescence assisted dispersive liquid−liquid microextraction method. Working theory was based on an acid-based reaction involving a proton donor and a carbon dioxide source. The paper outlines the considerations regarding the microextraction performance that can change in terms of physical, chemical properties, and its application for environmental sample analysis. A wide range of the developed and applied novel methods clearly indicates that CO 2 -effervescence is still in demand among researchers looking for new achievements in green analytical chemistry. This review focuses on the method application for the extraction and preconcentration of different classes of micropollutants (organic or inorganic) in environmental waters. New breakthroughs in the microextraction process show enhanced performance of the system in terms of sensitivity, accuracy, precision and the attempt to reduce extraction steps during separation or retrieval processes for low concentrations of analytes. Future direction refers to the improvement of green parameters in the microextraction, use of extracting agents as co-dispersers (solid or liquid), removal of elution dependency in solvents by the use of super-paramagnetic properties, etc. The success stories of the method development are widely documented in the literature. This microextraction technique will continue to serve as a reliable tool for the determination of micropollutants in environmental samples.
